A few points.

1 We are not alone: other forums suffer from the cookroom adverts as well as the nonsense today. I have seen someone say that they may be automated - even more stupid and inexplicable.

2 I need hardly say - Don't open the link in case they spread a virus into your computer.

3 Don't bother to reply to them or report as offensive: I look at the forum almost every day and will simply hide the thread and disable the account. More than that we can't do - so don't worry about it.
